The four-story ring (or Infinite Loop?) shaped Apple office building will cover roughly 3.1 million square feet and will feature green landscaping indoor and out, expanding the local campus form 4,500 trees to 7,500 by the time the project is complete in 2016. Appropriately, the local flora will include a wide variety of flowering fruit trees, including cherries, plums, and apricot trees, with persimmons. The campus will consist of 80 percent landscaping.

While the construction of the cutting-edge building won't wrap up until 2016, Norman Foster's firm gave Wired an exclusive sneak peek at the upcoming campus, via a series of design renders. The full collection can be found here, but here's some views from Foster + Partners via Wired.

Cars and buses approach the new headquarters in Cupertino, Calif.

An aerial view shows the main building.

Much of the new headquarters' parking is underground, to allow more green landscaping and "less disruption of natural spaces".

Many employees will arrive via local mass transit at a special entrance.

There will be above-ground parking at the southern side of campus as well.

Even that space will be covered in greenery.

A car approaches a vistor center. From here visitors will be directed to the visitor entrance at the main headquarters.

Visitors enter through a special entrance surrounded by flowering cherry trees.

Employees march in a separate entrance via white towering staircases.

The building facade is covered in curved glass panes. The industry standard for such panes is a 1/8th inch spacing, but Steve Jobs demanded a 1/32nd inch spacing, which required Foster + Partners to develop cutting edge glass laying techniques.
